A surface covering is a laminate including a hard inorganic wear layer deposited on a support by a reduced pressure environment technique such as ion assisted physical vapor deposition. The support may be selected from metal foils, films or sheets and plastics, rubbers or mineral/binder systems. The preferred support materials include organic materials. The wear layer is between 1 micron and 25 microns in thickness and has a CIE LAB value of total Delta E of less than 12. Preferably, the wear layer is deposited on the support at a temperature of less than 175 DEG C. The hard inorganic material may be an oxide, nitride or oxynitride, eg silicon oxide, aluminium nitride, silicon nitride or titanium nitride. The use of steel and tungsten is also envisaged. The surface covering may be used as a floor tile. The surface covering may also comprise an ink which diffuses into the support. The support may also comprise a decorative layer overlying the metal component. |
